Perfect fit!
My husband loved those. Very soft and comfortable. They run small, so be sure you check the sizing. I had to order him a 4XL, which he’s normally a 2XL in everything else.

Warm
I bought these for my husband who works out in the cold weather. He said they have helped keep him from being super cold on those freezing days.

Warm and comfortable
Just open them and put em on. Nice and soft, warm. Now I bought these as a base as I’ll be in 25 to 10 degrees Fahrenheit in the mountains. I am 6’2 280 pounds and ordered the 4x. I could have ordered the 3x and it would have been fine. Its 70 degrees in the house right now and I’m plenty warm and will probably have to take off the top. Honestly I thought I was just buying the pants part. Getting the top too seems like a bonus. And the top is nice and long to cover the waist of the pants. Sweet, no heat leak.

Works
Always used the cotton versions. This did even better and dosent get caught up on your clothes. I’d recommend.

Don’t order grey
I initially ordered a pair. They were great so I went to order two more and they kept sending me the wrong size. I was very disappointed. I canceled those orders and started a new order. for some reason when I ordered the gray, they would never come in my size just extra small, but now again, I am happy. I just ordered black and they came in the right size.

Incorrect size sent twice, don't buy these they will not be right!!!
Ordered these for my brother in a 4xl. Received them but in a medium. So obviously they wouldn't have fit him. So, I called Amazon to make a return and to make sure that I would be receiving the correct size that was ordered the first time. I was assured by Amazon rep that they would in fact be shipping a 4xl to me. Well, guess what still received a damn medium. Someone at ThermaJohn/Amazon is obviously not doing their job or they can't read. Will be returning this unusable product for a complete refund. I will not EVER purchase another product from ThermaJohn again. They can suck it for all I care. If this is how they do business then they should go out of business!
